"Game changing"
I saw Simon first doing a TED talk online. While the book is a bit repetitive, I think it might be by design. This concept is simple but VERY powerful. I constantly found myself talking about the concepts, which is always a good sign that the book is resonating with me. HIGHLY recommend it.
"Great story approach"
If you enjoy exploring ideas in the form of a story this is a great read. I find the story an approach a great way to have the reader apply their own ideas / experiences to the ones of the author. Great read!
"Couldn't get through the whole thing"
This book lacked any real design. It seemed like it was simply one comment after another about what not to do. Recommend you pass on this one.
"Lacked Structure"
I really liked the ideas in this book but I found myself looking for a but more structure. Ideas seemed to be delivered in no particular order. Would have been nice to build one concept on top of another. Still a good read though
